I doubt that bitcoin can rise again because every 3 years it can be seen decreasing for 1x. You can see the price of BTC in 2014 decreased by 45% - 47%
It is a good option actually to buy this low price and if yu if it has being falling then you should also see that last year aslo saw the highest price ever the btc has reached . So with he rise we do have the fall and this is how the crypto currency works as being volatile.
